It may not be common knowledge among Western visitors that the number "nine" carried a special significance in old China.
Ancient Chinese regarded odd numbers as being masculine and even numbers as being feminine. "Nine", which is the largest single
digit number was taken to mean the "ultimate masculine" and was, therefore, symbolic of the supreme sovereignty of the emperor. For
this reason, the number "nine" (or its multiples) is often employed in palace structures and designs. A noticeable example is the
number of studs on palace gates. The studs are usually arranged in nine rows of nine each, totalling eighty-one. This is even true of
the marble gates of the " underground palace" of the Dingling Mausoleum in Beijing: 81 (or 9 X 9) studs carved out of the stone. If
visitor go to the Temple of Guan Yu in Luoyang, he will also find on the red gate nine rows of nine wooden studs each. This was because Guan was given posthumous honours of an emperor.
Ancient palaces generally consist of nine courtyards or quadrangles which is the same as the Temple of Confucius in Qufu.
Shandong Province - a magnificent architectural complex worthy of an imperial household and testifying to the importance attached to
the great sage by the courts of various dynasties.
The buildings of the Forbidden City of Beijing are traditionally measured as having a total floor space of 9,900 bays. Some even
say 9,999 bays but this may be an exaggeration. The picturesque towers guarding the four corners of the palace compound each have
9 beams and 18 columns, and the three famous screen walls have nine dragons on each.
The number "nine" was sometimes combined with "five" to represent imperial majesty. The great hall on Tiananmen is 9 bays
wide by 5 bays deep.
There is a seventeen-arched bridge in the Summer Palace of Beijing. This too, has much to do with "nine". Count the arches
from either end, and you will find that the largest span in the middle is the ninth.
An extreme example of the "game of nine" is perhaps the Circular Mound Altar (Huanqintan) in the Temple of Heaven. Site for
the Ming and Qing emperors to worship Heaven, the altar is arranged in three tiers. The upper terrace is made up of nine concentric
rings of slabs. The first ring or the innermost circle consists of nine fan-shaped slabs, the second ring 18 (2 X 9) slabs, the third 27 (3 X
9)... until the last or ninth ring which is made up of 81 or 9 X 9 slabs.
The number "nine" is not only used on buildings. The New Year dinner for the imperial house was composed of 99 dishes. To
celebrate the birthday of an emperor, the stage performances must comprise of 99 numbers as a sign of good luck and long life.
